A lightning storm in Venezuela has been raging with incredible consistency since at least 1595. Known as “Relámpago del Catatumbo”, this mysterious storm located on the mouth of the Catatumbo river at Lake Maracaibo sees an estimated 1,176,000 electrical discharges per year. The lightning is a cloud-to-cloud arc that forms for 140 to 160 nights a year, 10 hours a night, and as many as 280 times an hour for centuries.

In fact, the lightning, visible from 400 kilometers away, is so regular that it’s been used as a navigation aid by ships and is known among sailors as the “Maracaibo Beacon.” Interestingly, generally little to no sound accompanies this fantastic light show, as the lightning moves from cloud to cloud—far, far above the ground.
